Scientists have created a new kind of ceramic coating that could pave the way for hypersonic travel for air, space and defense purposes.The finding could allow for the construction of a next generation of aircraft capable of travelling at 3,800 miles per hour (6,2000 km/h) or faster.Australia's Virtual Herbarium Australia-Japan Society of Victoria Australian Airconditioning | Security | Heating Australian Architecture Discussion Forum Australian Army Cadets - Victoria Australian Broadband Australian Bureau of Statistics Australian Businesswomen's Network Australian Centre for the Moving Image | ACMI Australian Chamber Orchestra | ACO Australian Communications and Media Authority (ACMA) Australian Dental Forum Australian Dictionary of Biography Online Australian Dismissal Services Australian Electoral Commission Australian Electoral Commission (AEC) Australian Feldenkrais Guild Inc.
The heat generated by air and gas in the atmosphere can have a serious impact on an aircraft or a projectile's structural integrity.In science fiction, even if a ship has shields that can shrug off atomic weapons, ramming it with another ship always manages to take it down. The impact of a heavy freight train going 60 mph is equal to that of 1 to 2 tons of TNT — it's just over a much smaller area, and going in one direction.Most spaceships are far heavier, and can go far faster.That said, there one challenge for a ramming ship, which is reaching the target in the first place.
At realistic space combat distances (hundreds if not thousands of kilometers), the target should have plenty of time to see the attempt coming and either blow up the ramming ship or dodge out of its way.
This would enable journey times from London to New York to be cut to just two hours, by racing to the edge of space before dropping back toward the Earth.
